The platform I2 is preferably mounted on the ridge of the roof with the two opposite sides parallel to the ridge, as shown, these sides each having a pair of depending flanges or lugs it which are parallel to each other and in planes at right angles to the ridge of the roof. A relatively long link or flat bar 18, having a hole near each end is attached by means of a bolt 20 to the outside of each of the lugs It, to provide a swinging pivot joint. These bars extend downwardly to the sloping surface of the roof to provide a pair of bars on each side of the ridge. The projecting ends of each pair of bars are attached by a pivot joint to a cross bar or plate 22 provided with flanges or lugs 24 which are similar to lugs it. The links or bars i8 are attached to the outside of the lugs 24 by means of bolts or pins 26, the lugs 24 on each bar 22 preferably being spaced the same as the opposite lugs Hi.

In mounting the platform l2 on the ridge of a roof the screws l4 are preferably first inserted to initially anchor the platform to the ridge with the links is and cross bars 22 extending onto the respective sides of the roof. The platform is then leveled crosswise of the ridge and the cross bars 22 are then secured flat side down to the sloping sides of the roof Ii] by means of screws 28 or other suitable attaching means. It will be noted that the pairs of links or bars l8 on each side of the roof pivot freely on the lugs l6 and that the cross bars 22 also pivot or rotate freely with respect to the links I8. The cross bars lie flat on the roof and are readily secured thereto, preferably under a slight tension, so as to hold the platform l2 rigidly upon the roof.

According to a preferred form of the invention, the platform is provided with a means for holding an antenna mast comprising a vertical section of pipe 34 which is welded or otherwise attached to the center of the platform l2, and which may extend substantially above the platform and receive an antenna mast 32. A set screw 34 is provided for retaining and anchoring the mast in the pipe 32.

The links is and cross bars 22 may be made of the same metal as the platform l2 and of substantially the same thickness, so as to provide a sturdy mounting. A relatively large platform is provided so that the sections extending along the ridge of the roof each side of the mast holder 39 aid in preventing the tipping of the mast in connection with the arms i8 which are mounted at the corners of the platform. The platform is also preferably relatively wide so that it extends over a substantial part of the sloping sides of the roof to provide a sturdy anchoring base for the attachment of the links or arms l8 which preferably are relatively long and extend a considerable distance down the slope of the roof. The angle between the platform and arms is preferably greater than 90. This angle of course will vary somewhat, depending upon the slope of the roof. The cross bars or plates 22 will always lie flat n the roof parallel to the ridge, and if desired, they may be attached to wooden cross pieces which in turn are attached to two adjacent rafters of the roof.

In Fig. 2, the improved mounting bracket is illustrated in connection with its use on the side of a sloping roof 3%. In this instance, one pair of the links is are omitted, and the cross bar 22 for that side is attached to the lugs H in place of the links. It will be noted that the flanges 24 on each cross bar 22 has the same spacing as the opposite flanges or lugs l6 and that in Fig. 2 the upper cross bar 22 is attached to the lugs is by an overlap on the same side of each lug It.

In mounting the bracket on the sloping side of the roof 36, in Fig. 2, the upper cross bar 22 is first attached to the roof by means of the screws 28 in substantially a horizontal position or so that the adjacent edge of the platform is level, after which the platform I2 is leveled off and the lower cross bar 22 then fastened to .the roof. It will be notedthat in each instance, the cross bars 22 in Fig. 2, lie flat on the same side of the roof and parallel to each other.

The platform I2 of the mounting bracket shown in Figs. 1 and 2 includes sets of holes 40 in addition to the holes for applying the screws l4. These holes 40 are positioned in arow each side of the center line of the platform l2 and are employed in the manner shown in Fig. 3 of the drawings to attach a pair of spaced wooden blocks or other members 42 to the under side of the platform parallel to the ridge of a roof 44. The use of the blocks 42 may be advantageous in certain cases where the ridge of the roof may be unsuited for the use of the screws l4. In Fig. 3 the bracket is shown as mounted on the roof 44 with the blocks 42 mounted symmetrically under the platform 42 and secured thereto by means of screws 46. The blocks 42 may be shaped in the manner shown so that a flat surface engages the under side of the platform while a sloping surface may be provided for engaging the sloping roof. In this illustration the blocks 42 will serve as a bearing for carrying the weight of the platform and the antenna mast while the links is and cross bars 22 are attached to the roof in the manner described above to anchor the platform in a level position. The blocks 42 extend the full length of the platform l2 and may have their lower side shaped to fit a particular roof. However, a standard shaped block may be employed, as for example, a half round wooden block in which the flat surface would be secured to the under side of the platform while the round surface would engage the roof. Where the ridge of the roof is constructed favorably, the blocks 42 may be first attached to the roof and afterwards have the platform I2 attached thereto as by screws 45.

The improved antenna mounting bracket of the present invention may be mounted in other ways than those illustrated, as will occur to persons skilled in the art. The drawings illustrate the facility of the bracket and the fact that it is readily installed on most any roof or other object where it may be desired to mount an antenna. Furthermore, a permanent and rigid mounting is provided which is easy to keep in proper condition and which is adapted to support and orient a complex antenna such as the dipole type used in connection with the transmission and reception of television and frequency modulation signals. Any antenna mast, if not round, may be readily trimmed to fit the pipe 3!! or be bored to fit over the pipe. A different form of mast holder may be welded or otherwise attached to the platform l2. A pipe mast may fit either on the inside or on the outside of the pipe section 39.

The platform l2, as an example, may be from eight to twelve inches long, in the direction of the ridge, and from six to ten inches wide across the ridge, and in fact may be square ifdesired. The links or bars I 8 may be from about five to ten inches long. While the platform is pref- Qnsaoae erably formed inthe manner shown with the integral lugs, suitablepivot; connections other than the flanges It may be; provided at the corners of the platform. The entire bracket is preferably made of a weather resisting steel, or

steel alloy, or it may be made; of duraluminum,

aluminum, bronz, cast iron, an it may be. plated, galvanized or painted,

The antenna mounting bracket of the present invention is relatively easy to manufacture since the platform is of simple construction and all of the links l8 are of the same size and shape, being nearly flat bars or plates, while the cross bars 22 are of the same stock and easily formed. In fact the arrangement may be such that the cross bars 22 are the same length as the bars or links it but are formed by bending the flanges 24 and drilling holes for the screws 28. The various changes and modifications indicated are contemplated as coming within the spirit and scope of the invention, as defined by the appended claims.
